docs(r3): PB-0 remediation program — Cluster M sequencing + §10 RED + option-(c) discipline + SG-0 tracker

[briansrls]

Summary

Director-greenlit partner work (#828 / #846 #issuecomment-4412008376) for the Pure-Bootstrap-Zero remediation program. Operator directive 2026-05-09: "course correct; existing plan stays canonical; staffing is not a concern; this is planning/correction." Branch-A from PR #2358 framing question: PB-0 by R3 close stays load-bearing.

Bundles 5 partner-work artifacts

#	Artifact	Status
1	docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md (NEW)	Task 1 — 3-phase plan with lane-Mgr partition
2	(Task 2 — worker briefs)	deferred — awaits Director ratification of dispatch shape per plan §8.1
3	ROADMAP.md:177 + scripts/check-pr-sg0-net-shrink-discipline.sh (AMEND)	Task 3 — option-(c) tightening
4	docs/r3-program-plan.md §10.3 (AMEND)	Task 4 — Risk 5 + Risk 6 + Cluster M reclassification rows
5	docs/audit/r3-sg0-trajectory-tracker.md (NEW)	Task 5 — daily-cadence schema + history + 3 threshold alarms

Key sequencing finding (Cluster M)

• Phase 1 (parallel): Substrate Mgr authors Fix gist #85 ForAll/Exists quantifier substrate canvas + BT1: SDLC pipeline compiles with unit_test profile #86 ProgramGenerator carrier canvas
• Phase 2: Verification Mgr authors RT1-RT4: model correctness — credential wiring, fail-closed auth, fil… #87 cementing-test discipline (consumes Fix gist #85/BT1: SDLC pipeline compiles with unit_test profile #86)
• Phase 3: Verification Mgr coordinates Implement SDLC pipeline: worker dispatch, stage handlers, and integration tests #84 bulk-port (~80-90 hand-Rust test entries dissolve)

Velocity: 4-8 weeks total Cluster M close; fits 8-12 week R3 window with parallel dispatch per operator's "staffing not a concern" directive.

Option-(c) tightening (closes the +30/9days paper-trail leak)

Per audit finding: SG-0 census grew +30 in 9 days because option-(c) "named follow-up dispatch" got paper-trailed without dispatch enforcement. Tightened: option-(c) now requires concrete dispatch evidence — gunbc#NNNN issue ref OR docs/briefs/*.md path. Self-tests pass.

Director ratification asks (per plan §8.1 + §9)

1. Dispatch shape choice — (α) single-coordinator brief / (β) 4 parallel-worker briefs / (γ) hybrid. PM recommends (γ).
2. Substrate canvas authoring authority — Substrate Mgr standing authority on Fix gist #85/BT1: SDLC pipeline compiles with unit_test profile #86 canvases, or Director-tier canvas-tier ratification?
3. Phase 3 bulk-port discipline — Verification Mgr coordinator (PM recommendation) vs distributed per-lane?
4. Implement SDLC pipeline: worker dispatch, stage handlers, and integration tests #84 closure criterion — fold Director-allocated test exceptions into closure-allowed, or testgen must cover them?

Authority + parents

Cites THESIS.md:298, ROADMAP.md:53/88/177, r3-program-plan.md §1.8 + §10, PR #2358 velocity-walk audit, PR #2300 cluster analysis as parents. Does not restate gate Pass-conditions or DAG shape.

Test plan

• Pre-push cargo fmt --all --check passed
• Self-tests for scripts/check-pr-sg0-net-shrink-discipline.sh pass with tightened (c) regex
• No code changes — docs + script + script self-test only
• §10.3 amendments use canonical row-format (column structure preserved)

1. Story of the diff

This PR turns the PB-0 velocity audit into a concrete remediation control loop. It tightens the SG-0 PR-window rule so option-(c) deferrals require a dispatch-tracker issue or queued brief evidence, then wires that into scripts/check-pr-sg0-net-shrink-discipline.sh with new pass/fail self-tests (ROADMAP.md:177, scripts/check-pr-sg0-net-shrink-discipline.sh:119-122, scripts/check-pr-sg0-net-shrink-discipline.sh:308-310). It also adds two audit artifacts: a Cluster M sequencing plan that decomposes Tests-As-Data closure into substrate-carrier, cementing-discipline, and bulk-port phases, and an SG-0 trajectory tracker that makes the census count/velocity visible (docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:23-28, docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:56-58, docs/audit/r3-sg0-trajectory-tracker.md:11). Finally, it updates the R3 program plan with gate-count canonicalization, the TC1 #11 “declared through R3” correction, and new §10 risk rows for PB-0 trajectory/Cluster M critical-path status (docs/r3-program-plan.md:86, docs/r3-program-plan.md:214, docs/r3-program-plan.md:1026-1028).

2. Invariant categories

1. LAYER MODEL — N/A. The diff does not introduce or modify Dag/substrate types, fields, variants, or Rust compiler modeling surfaces; it is documentation plus one CI validation script. The future substrate work is explicitly held behind substrate canvas/Director ratification instead of being modeled here (docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:73, docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:84, docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:95).
2. INVARIANTS.md + modeling-discipline.md — Finding, BLOCKING: P2 single-authority metadata / facts flow forward. The new gate-count canonicalization says 97 - 3 R4-carved (#81/#82/#95) = 94 R3-load-bearing and that gate #97 is part of that 94 (docs/r3-program-plan.md:86), but the same diff changes gate #11 to “DECLARED through R3” and says it is “not load-bearing for R3-thesis honest-close arithmetic” (docs/r3-program-plan.md:214). Those two lines cannot both be the canonical arithmetic unless Remove node override mocking mechanism from test framework #11 is either added to the carved/non-load-bearing set or the 94-count statement is revised. As written, the program plan has two authorities for what counts as R3-load-bearing closure.
3. CODING.md — Compliant. The shell validator remains explicit and fail-closed: after recognizing (c), it rejects missing dispatch wording and then rejects missing concrete evidence with return 1 rather than accepting a vague default (scripts/check-pr-sg0-net-shrink-discipline.sh:115-122).
4. TESTING.md — Compliant. The script change updates self-tests at the right level: one pass for brief-path evidence, one pass for issue-ref evidence, and one fail case for the formerly accepted vague lane-name deferral (scripts/check-pr-sg0-net-shrink-discipline.sh:308-310). It also preserves the following-line evidence case with the stricter brief-path form (scripts/check-pr-sg0-net-shrink-discipline.sh:323).
5. LOCKED DESIGN DECISIONS — N/A. The diff references thesis/R3 program decisions and Director ratifications, but it does not alter a locked substrate/design decision directly. The one canonical-plan inconsistency is covered above under single-authority metadata.
6. TRACKED vs UNTRACKED DEBT — Finding, NON-BLOCKING unless fragments are currently nonempty. The new SG-0 tracker claims to track the SG-0 census via EXPECTED_HAND_AUTHORED_NON_TEST + EXPECTED_HAND_AUTHORED_TEST only (docs/audit/r3-sg0-trajectory-tracker.md:11), and its generation procedure extracts only those two arrays (docs/audit/r3-sg0-trajectory-tracker.md:32-35). But the tightened SG-0 PR-window rule in the same diff describes the delta surface as EXPECTED_HAND_AUTHORED_* ∪ fragments (ROADMAP.md:177). If EXPECTED_HAND_AUTHORED_FRAGMENTS is part of the SG-0 ratchet, the tracker undercounts the live debt and can report “0 + 0” while fragment debt remains. Either include fragments in the tracker schema/procedure or explicitly state why fragments are out of scope for this trajectory artifact.

3. Verdict

REQUEST_CHANGES. The option-(c) enforcement and self-test update are directionally good, and the Cluster M sequencing plan is disciplined about not inventing substrate carriers in this PR. The gate-count canonicalization currently contradicts the TC1 #11 status change, though, so the canonical R3 closure arithmetic needs one source of truth before this lands.

[briansrls]

@briansrls (openai-pro REQUEST_CHANGES on sha 6efde884): both findings accepted + fix pushed at 5b10ed2da.

Finding 1 BLOCKING — §1.5 arithmetic vs row #11 contradiction: I added "97 - 3 R4-carved = 94 R3-load-bearing; #97 IS part of 94" alongside "#11 stays DECLARED through R3; not load-bearing for R3-thesis honest-close arithmetic" — two authorities for the load-bearing set.

Fix: refined §1.5 canonical breakdown to {97 enumerated → 94 post-R4-carve → 93 post-canvas-deferral}. Gate #11 added to a "post-R3-canvas-deferred" category alongside the R4-carved set; effectively removed from R3-thesis-honest-load-bearing arithmetic per Director (a)-disposition. Both 94 and 93 are canonical for distinct purposes:

• 94 = post-R4-carve enumeration count (used in R4-boundary discussions)
• 93 = R3-thesis-honest-close conjunction count (used in actual R3 close gate-count arithmetic)

The breakdown sequence cited explicitly in §1.5 to avoid +/-1 drift across closure-arithmetic citations.

Finding 2 NON-BLOCKING — SG-0 tracker fragments scope: Tracker procedure extracted only NON_TEST + TEST but ROADMAP.md:177 names the delta surface as EXPECTED_HAND_AUTHORED_* ∪ fragments. Tracker was undercounting.

Fix: added fragments column to tracker schema + procedure; updated history table with retroactive fragments=1 (per parse_parser_body.txt). New total formula: non_test + test + fragments.

Recommend re-review on current sha 5b10ed2da.

1. Story of the diff

This PR is mostly a PB-0/R3 control-plane correction: it reclassifies Cluster M as critical-path for zeroing Rust-authored tests, adds a sequencing plan for gates #84–#87, introduces a daily SG-0 trajectory tracker, and updates the R3 closure arithmetic around gate #11. The only executable change tightens SG-0 pairing: (c) in scripts/check-pr-sg0-net-shrink-discipline.sh so a net-add deferral must cite concrete dispatch evidence instead of just saying “follow-up dispatch” (scripts/check-pr-sg0-net-shrink-discipline.sh:111-121), with self-test coverage for brief paths and issue refs (scripts/check-pr-sg0-net-shrink-discipline.sh:308-310). The intended mechanism is good: make the remediation plan explicit, make SG-0 drift visible, and fail-close vague option-(c) deferrals. I found three consistency gaps in the new canonical docs / script contract that should be fixed before this becomes the authority.

2. Invariant categories

1. LAYER MODEL (substrate vs implementation).

N/A — the diff does not add or mutate substrate files, Dag-resident types, dag.rs, or new .dag variants. It discusses future substrate carriers for #85/#86, but routes them through a canvas/ratification path rather than landing substrate shape in this PR (docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:73-94).

1. INVARIANTS.md + modeling-discipline.md.

Finding — P2 Boundary Discipline / single authority: the R3 load-bearing gate count still has two authoritative meanings in the live §1.5 text. docs/r3-program-plan.md:84 still says (**94** are **R3 thesis-load-bearing**; **#81**/**#82**/**#95** are **R4-carved**), but the new canonicalization says **93 R3-thesis-honest-load-bearing** and defines R3 close as all 93 green at docs/r3-program-plan.md:91; the row for #11 also says Gate #11 stays DECLARED through R3 close; not load-bearing for R3-thesis honest-close arithmetic at docs/r3-program-plan.md:225. Keeping “94 are R3 thesis-load-bearing” in the primary total paragraph leaves the exact ambiguity the canonicalization is trying to eliminate. The fix is probably just to make line 84 say “94 post-R4-carve enumerated” or similar, and reserve “R3 thesis-load-bearing” for the 93 count.

Finding — P2 facts-flow-forward / single authority: the new SG-0 tracker includes fragments in the schema but drops them in the downstream math. The tracker defines the surface as EXPECTED_HAND_AUTHORED_NON_TEST + EXPECTED_HAND_AUTHORED_TEST + EXPECTED_HAND_AUTHORED_FRAGMENTS with target 0 + 0 + 0 at docs/audit/r3-sg0-trajectory-tracker.md:11, and the current snapshot row totals 48 + 101 + 1 = 150 at docs/audit/r3-sg0-trajectory-tracker.md:51. But §4 then says Current state ... 149 entries at docs/audit/r3-sg0-trajectory-tracker.md:55, says the close requirement is only 0 + 0 at docs/audit/r3-sg0-trajectory-tracker.md:57, and the progress-bar guidance says 149 → 0 at docs/audit/r3-sg0-trajectory-tracker.md:87. Since fragments are explicitly part of the ratchet, this should consistently be 150 → 0 and 0 + 0 + 0, or the doc needs a named projection that deliberately excludes fragments.

Finding — P2 boundary contract mismatch: option-(c) documentation accepts an issue URL, but the CI regex does not. ROADMAP.md:177 says option (c) may cite a dispatch-tracker issue URL OR queued pre-authored brief path, but scripts/check-pr-sg0-net-shrink-discipline.sh:119 only accepts gunbc#NNNN / #NNNN-style refs or docs/briefs/...md. A full GitHub issue URL such as https://github.com/gunb-ai/gunbc/issues/1234 follows the doc text but fails the script. Either the docs should say “issue ref” only, or the regex should accept the URL form too.

1. CODING.md.

Compliant, modulo the boundary-contract finding above — the script change keeps the gate as a simple input→verdict check: missing concrete option-(c) evidence emits an explicit error and returns nonzero (scripts/check-pr-sg0-net-shrink-discipline.sh:119-121) rather than silently accepting a vague deferral. The added self-test rows also make the intended pass/fail examples local to the script (scripts/check-pr-sg0-net-shrink-discipline.sh:308-310).

1. TESTING.md.

Finding — behavior-driven coverage misses one documented accepted shape. The new tests cover a brief path and gunbc#1234 issue ref (scripts/check-pr-sg0-net-shrink-discipline.sh:308-309) and reject a vague lane name (scripts/check-pr-sg0-net-shrink-discipline.sh:310), but there is no regression for the dispatch-tracker issue URL shape promised by ROADMAP.md:177. That is why the regex/doc drift above can land unnoticed.

1. LOCKED DESIGN DECISIONS.

Compliant — the diff does not silently alter a locked substrate/design decision. The #11 deferral is explicitly tied to the Director disposition and #1972 canvas-deferred state (docs/r3-program-plan.md:90, docs/r3-program-plan.md:225), and the Cluster M reclassification is recorded as Director-ratified rather than implied (docs/r3-program-plan.md:1039).

1. TRACKED vs UNTRACKED DEBT.

Compliant — the new planning scaffolds name their bounds and dissolution triggers: Cluster M phases are tied to gates #85/#86 → #87 → #84 with pass conditions (docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:32-51), the dispatch checklist names the ratification/dispatch sequence (docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:155-158), and the tracker gives cadence plus alarms instead of a vague “watch this” instruction (docs/audit/r3-sg0-trajectory-tracker.md:69-82). The open questions are explicitly marked for Director ratification (docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:168-174), so they read as tracked planning debt rather than hidden bridge state.

3. Verdict

REQUEST_CHANGES

The PR’s shape is right, and the option-(c) tightening is directionally correct, but the new canonical artifacts still disagree on the R3 load-bearing count, the SG-0 tracker drops fragments after declaring them in-scope, and the script/docs contract for option-(c) issue evidence is not aligned. These are small textual/script fixes, but they sit exactly on the PR’s load-bearing purpose: establishing trustworthy remediation arithmetic and fail-closed dispatch discipline.

[briansrls]

@briansrls (openai-pro REQUEST_CHANGES round 2 on sha 5b10ed2d): all 3 findings accepted + fix pushed at b925b1746.

Finding 1 — §1.5 line 84 ambiguity: removed "94 are R3 thesis-load-bearing" legacy framing; replaced with explicit three-canonical-number enumeration:

• 97 enumerated (full set)
• 94 post-R4-carve enumerated = 97 - 3 carved {#81, #82, #95}
• 93 R3-thesis-honest-load-bearing = 97 - 3 carved - 1 canvas-deferred {#11}

Finding 2 — SG-0 tracker §4 / §7 fragments inclusion: updated §4 to "150 entries (48 non_test + 101 test + 1 fragments)" + target "0 + 0 + 0"; updated §7 progress-bar guidance to "150 → 0". Tracker now fully consistent across schema (§1) / procedure (§2) / history (§3) / velocity math (§4) / progress-bar guidance (§7).

Finding 3 — script regex / ROADMAP boundary contract mismatch: expanded regex to accept https?://github.com/.../issues/NNNN form alongside gunbc#NNNN + docs/briefs/*.md. Updated error message + comment block. Added self-test for full GitHub URL form (run_case "(c) pairing with full GitHub issue URL" ... pass). Self-tests pass.

Boundary contract now aligned: ROADMAP says "URL OR brief path"; script accepts URL + issue-ref + brief path.

Recommend re-review on current sha b925b1746.

BLOCKING (2)

Root Cause

• docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md temporary exception handling is folded into the close condition → keep exceptions as blockers/non-close risk until the SG-0 test partition is actually zero.
• scripts/check-pr-sg0-net-shrink-discipline.sh dispatch evidence is reduced to a string pattern → require cited brief paths to exist in the checkout, or use an issue ref.

Non-blocking — Improvements (fix in-PR if easy, else defer to roadmap)

• docs/r3-program-plan.md Risk5 still cites 119→149 while the new tracker/ROADMAP surface includes fragments as 120→150; align the wording or explicitly say that count excludes fragments.

⚠️ The remediation direction is right, but the close condition and option-(c) enforcement still leave the PB-zero ratchet escapable.

[briansrls]

@briansrls (codex BLOCKING round 3 on sha b925b174): all 3 findings addressed + fix pushed at 5631cac33.

Finding 1 BLOCKING — close-condition exception fold:
Cluster M plan §1.3 #84 close criterion previously said "count = 0 (or carries only Director-allocated exceptions)" — folding exceptions into close-condition leaves PB-zero ratchet escapable. Tightened to strict zero; Director-allocated timed-carries (e.g., Option 2 cross_target_coverage_carrier_test.rs) are now blockers/non-close-risk until they migrate to testgen-coverage. R3-honest-close requires actual zero, not "zero-except-exceptions." §5.1 receipt language updated to match.

Finding 2 BLOCKING — dispatch evidence reduced to string pattern:
Brief paths cited in option-(c) pairings now require file existence verification at $ROOT/$path. String-pattern match alone was escapable (cite a fictional brief path, satisfy regex without authoring). Issue refs / GitHub URLs are external and not file-checkable here, so they pass through pattern check only. Updated script self-tests to use real brief path (docs/briefs/r3-v-tests-as-data-v1-worker.md); added new fail case for nonexistent brief path:

run_case "(c) cited brief path that does not exist (tightened 2026-05-09 codex BLOCKING)" \
  $'SG-0 hand-path delta: +1\nSG-0 pairing: (c) follow-up dispatch via docs/briefs/r3-nonexistent-brief-2026.md' \
  fail

Self-tests pass.

Finding 3 NON-BLOCKING — Risk5 numbers misaligned with fragments-inclusive surface:
§10.3 Risk5 cited 119→149; tracker + ROADMAP surface (post-fragments-inclusion) is 120→150. Updated Risk5 row to fragments-inclusive numbers with provenance citation.

Boundary contract now consistent: close-condition matches "actual zero" semantics; script enforces file-existence for brief-path evidence; Risk5 numbers match canonical surface.

Recommend re-review on current sha 5631cac33.

@briansrls (codex inline BLOCKING @ docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:58 on sha b925b174): same finding as the top-level codex BLOCKING (Finding 1) — both flag the "Director-allocated exceptions satisfy closure" language. Already addressed at sha 5631cac33 (commit 5631cac33 on this branch HEAD).

- **#84 closes when bulk port runs to zero — strict**: state-check gate ... 
  Closes when SG-0 census `EXPECTED_HAND_AUTHORED_TEST` count = 0.
  **Per codex BLOCKING on PR #2361 sha `b925b174` (2026-05-09)**: temporary
  exception handling (e.g., Director Option 2 timed-carry tests like
  `cross_target_coverage_carrier_test.rs`) is **NOT folded into close
  condition** — exceptions remain blockers / non-close risk until SG-0 test
  partition is actually zero. R3-honest-close requires the count itself to
  reach zero, not "zero except exceptions." Director-allocated timed-carries
  must dissolve via testgen-coverage migration before #84 fires; otherwise
  #84 remains DECLARED.

Strict-zero close-condition restored; PB-zero ratchet no longer escapable via Director-allocated exception fold.

The pattern-match check at line 119 still gates input shape (must contain at least one of: issue ref / GitHub URL / brief-path token). The new file-existence loop at lines 126-135 verifies that any cited docs/briefs/*.md token actually resolves to a file in the checkout.

Self-test coverage:

• (c) cited brief path that does not exist — fail (new test, post-5631cac33)
• (c) pairing with existing brief path — pass (uses docs/briefs/r3-v-tests-as-data-v1-worker.md)

Fabricated brief evidence is now rejected. Issue refs / GitHub URLs remain pattern-match-only (external; not file-checkable here).

BLOCKING (2)

Root Cause

• docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md Exception handling remains in the closure-criterion decision surface after strict-zero was chosen → rewrite §9.3 as an execution-risk question that assumes exceptions block #84 until migrated to TestClaim/testgen coverage.
• scripts/check-pr-sg0-net-shrink-discipline.sh Dispatch evidence validation treats a matching path string as brief-queue authority → reject traversal/absolute paths and canonicalize each cited path to ensure it remains under $ROOT/docs/briefs.

ROADMAP — Verified

• SG-0 fragments-inclusive surface: ROADMAP.md and the new tracker now include EXPECTED_HAND_AUTHORED_FRAGMENTS in the PR-window and 120→150 trajectory accounting.

⚠️ Two small inconsistencies keep the PB-zero ratchet escapable: the Cluster M doc still reopens #84 exception closure, and option-(c) brief evidence needs path containment as well as existence.

[briansrls]

@briansrls (codex inline BLOCKING @ docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:174): finding accepted + fix pushed at 296f72fa8.

§9.3 was left open after the prior round's 5631cac33 fix tightened §1.3 + §5.1 to strict-zero close-condition. The open question contradicted the resolved language. Internal close-authority within the doc was inconsistent.

Fix: marked §9.3 RESOLVED 2026-05-09 with cross-reference to canonical close-condition at §1.3 + §5.1. Question is no longer open. Strike-through retains the original framing for audit-trail readability:

3. ~~#84 closure criterion under Director-allocated exceptions~~: RESOLVED 2026-05-09 ...
   strict-zero close-condition adopted: Option 2 timed-carry tests are NOT folded into
   close-condition; they remain blockers / non-close-risk until testgen-coverage migration.
   See §1.3 + §5.1 for canonical close-condition. This question is no longer open.

Internal close-authority now consistent across §1.3 (canonical close-condition) + §5.1 (Phase 3 receipt) + §9.3 (resolved-not-open).

@briansrls (codex inline BLOCKING @ scripts/check-pr-sg0-net-shrink-discipline.sh:119): finding accepted + fix pushed at 315ba2a52.

Issue: regex docs/briefs/[[:alnum:]_./-]+\.md permitted .. path-traversal tokens. Existence check would then resolve docs/briefs/../foo.md → docs/foo.md which could exist as a non-brief file. P5 tracked-deferral discipline requires the cited path actually be a queued brief under docs/briefs/, not just any existing markdown file.

Fix (defense-in-depth, three orthogonal checks):

1. Reject .. segments — explicit grep (^|/)\.\.(/|$) rejection of path-traversal tokens
2. Canonical-prefix check — [[ "$p" != docs/briefs/* ]] rejection (redundant with regex but guards future regex relaxation)
3. File-existence check — retained from prior round

New self-test added: "(c) cited brief path with path-traversal (.. segment)" expects fail. Prior self-tests still pass:

$ bash scripts/check-pr-sg0-net-shrink-discipline.sh --self-test
check-pr-sg0-net-shrink-discipline.sh: self-test OK

Brief-path option-(c) discipline now enforces three orthogonal properties: (a) prefix-locked under docs/briefs/, (b) path-traversal-free, (c) file-existing. Prior escape paths (fictional brief, path-traversal, prefix-mismatch) all closed.

Recommend re-review on current sha 315ba2a52.

@briansrls (codex top-level BLOCKING on sha 5631cac3 consolidating 2 inline findings): both already addressed across 2 fix commits + verified via grep. Roll-up:

Finding 1 — §9.3 exception closure question (inline @ line 174): reopened the #84 closure-exception question after §1.3/§5.1 made strict-zero the close-condition. Fixed at 296f72fa8 (#issuecomment-4412292644): §9.3 marked RESOLVED with cross-reference to canonical close-condition; question is no longer open. Internal close-authority now consistent across §1.3/§5.1/§9.3.

Finding 2 — brief-path canonicality (inline @ script:119): regex permitted docs/briefs/../*.md path-traversal; existence check alone insufficient. Fixed at 315ba2a52 (#issuecomment-4412301847): added 3-check defense (path-traversal rejection + canonical-prefix check + file-existence). New self-test for path-traversal rejection passes:

$ bash scripts/check-pr-sg0-net-shrink-discipline.sh --self-test
check-pr-sg0-net-shrink-discipline.sh: self-test OK

ROADMAP fragments-inclusive surface — codex's "Verified" note confirms 120→150 trajectory accounting + ROADMAP fragments-inclusive surface holds.

Net status on current sha 315ba2a52:

• Cluster M plan §9.3 — resolved (no contradictory open question)
• Script option-(c) brief-path — three orthogonal checks (canonical-prefix + traversal-free + file-existing); prior escape paths all closed
• ROADMAP fragments-inclusive — verified

Both BLOCKING items addressed; PB-zero ratchet escape paths closed. Recommend re-review on current sha 315ba2a52.

BLOCKING (2)

Root Cause

• docs/r3-program-plan.md Carve-promotion amendment was appended below stale carve arithmetic instead of replacing it → make §1.5 use one canonical count surface: 97 enumerated, 0 carves, 1 deferred, 96 load-bearing.
• scripts/check-pr-sg0-net-shrink-discipline.sh Issue evidence grammar treats any #number as dispatch authority → require explicit tracker/issue syntax and add a gate-number false-positive self-test.

ROADMAP — Verified

• SG-0 fragments-inclusive surface: The tracker and ROADMAP amendment include EXPECTED_HAND_AUTHORED_FRAGMENTS in the SG-0 delta/accounting surface.

⚠️ Two small authority holes remain: §1.5 still carries conflicting close arithmetic, and option-(c) evidence can still be satisfied by a gate-number mention.

[briansrls]

@briansrls (codex inline BLOCKING @ docs/r3-program-plan.md:86): finding accepted + fix pushed at 2e782f219.

Issue: §1.5 intro paragraph still listed "97 / 94 / 93" three-number framing while the canonicalization block below said "0 R4-carved / 96 R3-thesis-load-bearing" — two competing authorities for R3 gate arithmetic. The 94/93 framing was stale post-Director carve-promotion-IN-R3 ratification at c#4412330468; should have been removed when canonicalization block was added but I missed the intro paragraph.

Fix: §1.5 intro now consistent with canonicalization block:

"97 enumerated (the full set; all R4 carves dissolved per Director ratification 2026-05-09)
96 R3-thesis-load-bearing = 97 − 1 (only canvas-deferral subtracted; gate #11 TC1 V1 strict-fire per Director (a)-disposition 473b99fb...)"

"No R4 carves at R3 close per Director ratification 2026-05-09 c#4412330468 — gates #81/#82/#95 (formerly R4-carved as C1/C2/C3) are PROMOTED-IN-R3 as lens-producer-retirement work folded into Cluster F."

Single authority restored. The "94 post-R4-carve" intermediate count explicitly marked as superseded.

Recommend re-review on current sha 2e782f219.

BLOCKING (1)

Root Cause

• docs/r3-program-plan.md carve-promotion canonicalization landed only in the new §1.5 overlay while downstream closure authorities were left unchanged → update §1.8 rows/close formula and the referenced r3-structure/r4-carve routing, or keep the prior carved arithmetic.

⚠️ The SG-0/script fixes look solid, but the R3 close arithmetic still has contradictory authorities after the no-carves canonicalization.

openai-pro REQUEST_CHANGES on c6c3fb96 — review-input tooling block, not content finding

The verdict explicitly states "This is not a content objection to the PR; it is a review-input block. I cannot approve a PR review when the target diff is unavailable" — openai-pro's session got 404 fetching pr-2361.diff.

This is a tooling-side issue, not a PR content issue. Verification:

• PR docs(r3): PB-0 remediation program — Cluster M sequencing + §10 RED + option-(c) discipline + SG-0 tracker #2361 sha c6c3fb96 is MERGEABLE per gh pr view 2361
• Prior openai-pro review at sha ba18ef86 (2026-05-09T12:11:43Z) successfully fetched the diff and produced substantive content findings (REQUEST_CHANGES on URL-regex breadth, addressed at sha c6c3fb964)
• The PR is accessible via standard GitHub UI + API endpoints (gh pr view 2361 / /pulls/2361/files)
• The .diff URL pattern can return 404 in private-repo contexts even when the PR itself is fully accessible — depends on auth path
• All inline review comments from codex / openai-pro on this PR have completed successfully prior to this run

Path forward

Re-trigger openai-pro review on sha c6c3fb964 (current HEAD) — the prior tool path worked at ba18ef86, so this is likely a transient fetch issue. Per dashboard quorum criteria: this is not a substantive REQUEST_CHANGES; it's a no-content review-input block. Fresh re-review needed for substantive verdict on the URL-regex tightening at sha c6c3fb964.

Substantive content state at HEAD c6c3fb964

Prior round-1 openai-pro REQUEST_CHANGES (URL regex too broad) addressed:

• Regex tightened from https?://github\.com/[[:alnum:]_./-]+/issues/[0-9]+ to https?://github\.com/gunb-ai/gunbc/issues/[0-9]+

Codex BLOCKING (single-authority drift) addressed at sha 06e3db206

Codex inline BLOCKING @ docs/r3-program-plan.md:99: "the new 96/no-carves close target is not propagated to the later §1.8 close formula or the referenced r3-structure/r4-carve authorities that still mark #81/#82/#95 carved, leaving two R3 close authorities (INVARIANTS P2 single authority)."

Root cause

PR #2361's §1.5 canonicalization block (added at sha 2e782f219 per Ask 9) introduced "96 R3-load-bearing / 0 carves" framing but didn't reconcile parallel-authority references elsewhere.

BLOCKING (1)

Root Cause

• docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md Cluster M sequencing was authored from the velocity audit without absorbing the existing tests-as-data design authority → cite docs/design-tests-as-data-completeness.md as canonical and limit the plan to sequencing/implementation deltas, or explicitly supersede that authority in the same chain.

⚠️ The prior blockers are addressed, but the new Cluster M plan needs to reconcile with the existing tests-as-data design authority before merge.

[briansrls]

BLOCKING: §3 reopens #85/#86 carrier-shape and Director-ratification questions even though docs/design-tests-as-data-completeness.md already canonically defines ProgramGenerator/Quantifier/QuantifiedTestClaim and says no Director ratification is required before lane dispatch, creating a second authority for the lane plan (INVARIANTS P2 single authority).

[briansrls]

Codex BLOCKING (single-authority for #85/#86 carrier shape) addressed at sha 697a12570

Codex inline BLOCKING @ docs/audit/r3-cluster-m-sequencing-plan-2026-05-09.md:92: "§3 reopens #85/#86 carrier-shape and Director-ratification questions even though docs/design-tests-as-data-completeness.md already canonically defines ProgramGenerator/Quantifier/QuantifiedTestClaim and says no Director ratification is required before lane dispatch, creating a second authority for the lane plan (INVARIANTS P2 single authority)."

Verification

docs/design-tests-as-data-completeness.md exists on main (git ls-tree origin/main confirms blob ff49723d4019):

• §1 Authority discipline: "All §8 design questions resolved in-doc per feedback_design_before_implement — no Director ratification required before lane dispatch (only standard cascade gates: R2-Evaluator landed; existing TestClaim infrastructure from DB-15 R2)."
• §2.1 canonically defines ProgramGenerator (structural reference to generator declaration; not a roster)
• §2.2 canonically defines Quantifier (closed two-variant ForAll | Exists sum) + QuantifiedTestClaim { generator, quantifier, ... }

Root cause

My §3.1/§3.2 framing as "substrate canvas needed; Director ratification needed before brief authoring" was a duplicate-authority anti-pattern — should have grep-verified locked design before authoring canvas-tier framing. Per feedback_grep_verify_locked_design_before_ratification (the same pattern that surfaced earlier in this session on PR #2363 C2 audit).

Fix at 697a12570 — 16 insertions / 24 deletions across:

• §3 header + intro: citation to locked design + authority-correction note
• §3.1/§3.2: rewrote from "substrate canvas needed + Director ratifies" → "carrier landing per locked design §2.1/§2.2; no Director ratification needed; standard cascade gates only"
• §2 Lane-Mgr partition table: authoring scope cites locked design
• §2 closing prose: "no canvas-tier ratification — design-doc resolves shape per §1 Authority discipline"
• §4: "carrier landings per locked design not blocking" instead of "substrate canvases for Fix gist #85/BT1: SDLC pipeline compiles with unit_test profile #86 not blocking"
• §6 velocity projection: "carrier landings per locked design" instead of "substrate canvas + carrier authoring"
• §6 risk: replaced "canvas-tier ratification adds 1-3 days" with "STOP-and-PING via Substrate Mgr inbox if migration shape surprises arise per feedback_construction_over_ratchets"

Single canonical authority restored

Locked design docs/design-tests-as-data-completeness.md §2.1/§2.2 owns ProgramGenerator/Quantifier/QuantifiedTestClaim shape; this sequencing plan owns Cluster M phase ordering only.

Cross-PR cascade note

PR #2362 (3 dispatch briefs for Cluster M) may inherit similar canvas-tier framing — will verify and cascade-fix on that PR if needed.
